IMPROVEMENT IN EASY-CHAIRS.

Specification forming part of Letters Patent No. 196,468, datedSeptember 25, 1877; application filed July 5, 1877.

To all whom it may concern Be it known that I, GILBERT A. WATER- HOUSE,of Quincy, in the county of Norfolk and State of Massachusetts, haveinvented an Improvement in Easy-Chairs, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification, in which-Figure l is a perspective view of an easychair constructed in accordancewith my invention, and Fig. 2 a vertical section through the center ofthe same.

This invention consists in an easy-chair in which one end of the stripof flexible material which forms the seat and back is attached to arocking frame pivoted between the sides of the frame of the chair, theupper end of the flexible strip being secured to the frame of the chairat or near the top of the back, by which construction a rocking movementof the seat can be effected by the occupant of the chair, and much easeand comfort thereby afforded.

To enable others skilled in the art to understand and use my invention,I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents the frame of the chair, between theside bars b b of which extends a rod, 0, on which is pivoted a rockingframe, B, the end pieces (1 of which are curved, as shown. To the frontend of this frame B is securely fastened one end of a strip, 0, ofstrong flexible material, which forms the seat and back of the chair,the upper end of the strip 0 being attached to the top bar e of the backof the frame A, and the strip being allowed to hang loosely between thepoints, where its ends are secured, in order to give the required shapeto the seat and back, as seen in Fig. 1. f is a spiral spring, one endof which is secured to the rocking frame B, and the other end to the bar9 of the frame A, this spring serving to keep the parts in the positionseen in Fig. 1 when the chair is not in use.

From the foregoing it will be seen that the pivoted frame B will allowthe occupant to rock or tilt the seat back and forth, or adjust it toany desired position; and a chair thus constructed combines ease andcomfort with strength and simplicity of construction.

If desired, the spring f may be dispensed with but I prefer to use it,as it insures the rocking frame B being returned to a central positionafter being tilted forward, and keeps the seat in its proper positionwhen the chair is unoccupied.

What I claim as my invention, and desire to secure by Letters Patent,is-

The rocking frame B, pivoted between the sides of the frame A, andprovided or not with a spring, f, in combination with the flexible strip0, forming the seat and back of the chair, and having one end attachedto the rocking frame B, and the other end to the stationary frame A,substantially as and for the purpose described.

Witness my hand this 3d day of July, A. D.
